Exactly. Emblem.js is for people who love Haml / Slim / Jade and want to use that style of templating with Handlebars.js
It really fits into place if you're coming from one of those libraries. I only wish I could enable percent-sign indicators for HTML tags! (%h1 vs h1)
%h1 is totally valid emblem syntax.
edit: it's optional, of course, but you have to use it if you need to use non-standard (read: unrecognized by emblem) html tags
Not sure how I missed that. It's a kick-ass little feature in my book, because while I appreciate the "implied HTML tags", I do find them easy to miss.
